Police union leaders have called a press conference this afternoon to discuss a controversial Oct. 30 welfare check at the home of NAACP Rockford Chapter President Lloyd Johnston.Leaders of the Police Benevolent and Protective Association Unit 6 that represents the Rockford Police Department's roughly 280 police officers have raised questions about Chief Chet Epperson's role in the episode and whether he obstructed officers from doing their jobs.They have also objected to officers being questioned in regard to how they handled the call.An officer wrote in his police report that he heard Epperson advising Johnston over speaker phone not to "let them in the house and tell them to leave" while Epperson sent a supervisor to the scene.Johnston said Epperson did not tell the officers to leave.But Johnston did decline to allow the officers into his home. Unbeknownst to Johnston at the time, the officers had been sent there after a call from his ex-wife from New York to check on the well being of their adult son with whom it was falsely said there was a "history of physical domestics."Officers had asked to enter the home to explain why they were there, with Officer D'Eveyron Boone telling Johnston they would "kick the door in" if needed.That's when Johnston called Epperson and conducted a conversation by speaker phone.Johnston had participated in an NAACP public safety campaign over the summer meant to reduce conflict with police and the potential for officer involved shootings by better educating residents on their rights and what to expect from police.Among those rights is the Fourth Amendment protecting U.S. citizens from unreasonable searches and seizures. And the campaign encouraged people to learn the phrase "I do not consent to searches."Once Sgt. Eddie Torrance arrived at Johnston's house, it was explained that police have a community caretaker function and that officers could not leave until checking the condition of Johnston's son. He came outside and when police saw he was OK, the situation was resolved.Questions about what happened continue to linger as an internal police investigation is said to be on-going.Follow my coverage of the press conference today starting at 1:30 p.m. on Twitter and at rrstar.com.
